Jennifer Lawrence ended her birthday party in bed with Kris Jenner.

The 'Hunger Games' actress is a big fan of the matriarch and her TV series 'Keeping Up with the Kardashians' so her pals arranged for a special guest of honour at her celebrations at a private Hollywood house.

A source revealed: ''Jen celebrated her birthday with a bunch of her closest friends at a private home in the Hills. Her friends actually reached out to Kris Jenner to invite her to celebrate Jen's birthday since Jen is such a reality TV junkie and loves 'Keeping Up With the Kardashians'.''

After consuming lots of wine, Kris became ''very tipsy'' according to the source and she later shared a photo of the Oscar-winning actress hugging her in Jennifer's bed.

A source told Us Weekly magazine: ''Kris arrived after just having landed back in L.A.. She was drinking lots of white wine and got very tipsy. She even got to a point where she said, 'I have to stop drinking!' Kris asked Jen to be her date to the FYF Fest Sunday to see Kanye [West] perform too!''

The 59-year-old momager wrote next to the photo on Instagram:''Happy Birthday you piece of s***t... God I love you #Jenniferlawrence thanks for making this night a night to remember.....even if we did get caught... I love you Happy Birthday Gorgeous!!! #Bible #momager #doll. Photo cred @coreygamble (sic)''

Meanwhile, an insider shared what else the 'Silver Linings Playbook' star - who turned 25 on August 15 - got up to, including ''dancing'' and ''karaoke''.

The insider added: ''Jen really had a blast laughing and dancing with Kris. They even did karaoke together and just laughed the whole night.''
